Product details
Overview
BAT63-02V E6327 from Infineon Technologies is a silicon Schottky barrier diode optimized for zero-bias RF detection up to 2.4 GHz, with 0.65 pF typical capacitance at 0.2 V, 30 kΩ typical differential resistance at 0 V, and 190 mV typical forward voltage at 1 mA - deployed in microwave receiver front-ends and RFID tag detectors.
For engineers reviewing the BAT63-02V E6327 datasheet, BAT63-02V E6327 pinout, BAT63-02V E6327 application, or BAT63-02V E6327 equivalent, key selection criteria include low-voltage zero-bias detection capability, sub-1 pF junction capacitance, matched VF performance in dual-diode configurations, and SC79 package thermal resistance of ≤295 K/W.
Technical Context
This diode operates without DC bias, leveraging its low-barrier Schottky structure to rectify RF signals directly - enabling detector circuits in 2.4 GHz ISM-band receivers. Its 0.65 pF capacitance and 30 kΩ zero-bias resistance support high-frequency impedance matching and minimal signal loading.
The device is configured as a single diode in SC79 (SOT-343) package with anode-cathode-anode-cathode terminal layout. Thermal resistance from junction to soldering point is ≤295 K/W, supporting operation up to 150°C junction temperature under 100 mW total power dissipation.
Key Specifications

| Forward Voltage @ 1 mA | 190 mV typ. - enables near-zero-bias operation with minimal threshold penalty |
| Junction Capacitance @ 0.2 V | 0.65 pF typ. - ensures minimal capacitive loading on 2.4 GHz antenna interfaces |
| Differential Resistance @ 0 V | 30 kΩ typ. - provides high dynamic impedance for efficient RF-to-DC conversion |
| Reverse Current @ 3 V | 10 µA max. - maintains low leakage in battery-powered detector stages |
| Total Power Dissipation | 100 mW - supports continuous operation within SC79 thermal limits at TS ≤ 120°C |
| Junction Temperature Limit | 150°C - defines maximum allowable die temperature during pulsed or CW RF detection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar zero-bias RF detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Avago (Broadcom) HSMS-2850 | Higher CT (0.95 pF typ.), lower R₀ (22 kΩ typ.), same SC79 package | Slightly reduced high-frequency sensitivity above 2 GHz due to higher capacitance | Prefer when tighter VF matching across production lots is required (±5 mV vs ±20 mV) |
| Skyworks SMS7621-011 | Lower VF (150 mV typ.), higher IR (20 µA max.), SOD-323 package | Requires re-layout for different footprint; better sensitivity but higher leakage in low-duty-cycle apps | Choose for ultra-low-threshold detection where board space allows SOD-323 placement |
Compared with HSMS-2850 and SMS7621-011, BAT63-02V E6327 delivers optimal balance of low capacitance, moderate differential resistance, and proven thermal robustness in SC79 - making it preferred for compact, thermally constrained 2.4 GHz detector designs requiring long-term reliability.

FAQ
Is BAT63-02V E6327 suitable for 5 GHz operation?
No. Its junction capacitance and series inductance limit effective use to ≤2.4 GHz. At 5 GHz, measured insertion loss exceeds 3 dB and detector sensitivity degrades significantly due to parasitic resonance - confirmed by Infineon's application note AN2011-06, Figure 5.
What is the meaning of "E6327" in the part number?
E6327 is Infineon's internal tape-and-reel packaging code indicating 3,000 pieces per 180 mm reel, standard moisture sensitivity level (MSL 1), and Pb-free finish - not a functional variant. Electrical specs match BAT63-02V base type.
Can BAT63-02V E6327 replace BAT63-07W in existing designs?
Only if the design uses a single diode. BAT63-07W integrates two diodes in parallel pair configuration (lower RthJS = 355 K/W, higher IF rating). BAT63-02V is single-diode with superior thermal resistance (≤295 K/W) but no internal parallel path - verify current sharing in detector load networks.
Does this diode require ESD handling precautions?
Yes. The BAT63-02V E6327 is classified as ESD-sensitive (Class 1B per JEDEC JS-001), with failure threshold <500 V HBM. Handling requires grounded wrist straps, dissipative mats, and ionized air - as explicitly stated in Infineon's 2011-06-15 datasheet page 1.
